3-Wire Configuration
Most older homes had 240 volt kitchen oven circuits wired with a 3-wire cable consisting of 2-hot wires and a ground wire. Fortunately most electric ovens can be wired to work with either a 3-wire or 4-wire circuit.


4-Wire Configuration
All new installations require a 4-wire 240 volt circuit circuit which has a separate insulated neutral wire and the separate ground wire along with the 2-hot wires of the appropriate wire size depending on the oven that is being installed.

In some cases where the home is older than the new electric oven here's what you would have to do: Where the wires are connected to the electric oven you will need to install the Bonding Crimp Sleeve to Bond the Grounded Wire and the Neutral Wire as shown in the 3-WIRE HOOK UP wiring diagram below. The Grounded Wire is attached to the metal frame of the electric oven internally and is usually located inside the oven junction box enclosure.

IMPORTANT:
The following steps apply ONLY if the oven specifically states that it can be wired for either 3-Wire OR 4-Wire Connections. Some new ovens may require a Separate Insulated Neutral Wire AND a Separate Ground Wire for a 4-Wire Connection Only.

The oven shown here can be wired for a 3-wire connection or a 4-wire connection as described in the attached wiring specifications.

Be sure to consult your oven installation manual
specifications for the configuration that is allowed.

Below are examples of the most common situations:
Converting an older
240 volt 3-wire circuit
to a new electric oven with 4-wires. Typically the newer oven will allow the ground and neutral to be bonded together and connected to the ground wire of the 240 volt circuit. 		Converting a newer
240 volt 4-wire circuit
to an older electric oven with 3-wires.
The white or neutral wire of the circuit is capped off and not used.

Questions and Answers about How to Wire an Oven

Question:

Can a Oven Circuit be Used for a Water Heater?


Glen asks: I have a 220 volt circuit coming in to my oven, can I use that line to provide power for a water heater?

Answer:
No, you cannot do this. Each of these devices needs to have their own dedicated circuit of power, and they both have their own specified amount of power. The water heater requires a dedicated 30 amp 240 volt circuit. Placing the water heater on the same circuit as the oven will overload the oven circuit and cause it to trip the circuit breaker off.
Question:

What are the Wiring Connections for a 240 Volt Oven?


Daniel asks: I have a 1980's Home, with a 3-wire 240 volt circuit which is Aluminum. I would like to know how to connect his cable to my new stove.
The Cable Wires are:
1-black insulation, 1-black with 2 red lines insulation and a bare ground.
Does the black wire with red lines go to red on stove? Does it matter if the 2 hot are switched?

Answer:
Daniel, here is the typical 240 volt wiring connections:

Circuit Black wire to Black wire of the Oven.
Circuit Black with Red to Red wire of the Oven.
Circuit Ground, Green or Bare wire with Oven Green or Bare.
* It does not matter if the Black and Red wires are reversed with 240 volt oven wiring.
* Some 4-wire ovens do permit bonding the White Neutral wire to the Ground wire. Check the Electrical Connections in your installation manual to be sure.

New and Updated about: Wiring an Oven

Question from Greg, a Handyman from Tigard, Oregon:
Is it OK to install a new 4-wire oven, with black, red, white and green wires?

I just removed a wall oven in a house built in 1994. I discovered that the supply to the junction box for the oven (on its own separate circuit) is Type SE 8AWG aluminum, with two black wires and the neutral being the twisted-strand insulated type. It is my understanding that NEC allows me to install a new 4-wire oven, with black oven wire to black, red oven to black, and white/green oven to insulated. Also, that I should coat the connections with an anti-oxidizing compound and use special purple wire nuts. Is this correct?

Dave’s Answer:

Greg, This depends on the oven that you have. Some ovens require a separate insulated neutral wires and a ground. Consult the installation manual that came with the oven for specific details.
Anti-corrosion compound is required when splicing aluminum and copper wires together, and the wire connector must be UL Rated for AL/CU wires.

Question from Rod, a Homeowner in Woodsboro, Maryland:
What are the proper wire connectors that should be used when hard wiring a double wall oven?

This is a new kitchen renovation and I am replacing old aluminum wiring with 6 AWG copper 4-wire on 50 amp 240 volt breaker. Should I be using a block splice with shrink tubing? A copper split bolt seems bulky? Even the largest wire nuts seem inappropriate. Is a 4″ box large enough, those wires are not very flexible. I will be doing the same type of hook-up for an induction cooktop.

Dave’s Answer:

The large blue connectors are typically used to make the connections for the oven wires to the oven circuit wires. Be sure to trim the insulation back and join the wires together side by side and then apply the wire connector by twisting in the clockwise direction. Install a junction box that has the required cubic inches for the total number of wires that will be enclosed inside the box.

Question from Joe, a Homeowner from Inarajan, Guam:
Which cable should I use for an oven circuit?

What number Romex wire do I use to install an oven? What is the correct amperage?
What is the required Romex wire?

Dave’s Answer:

Joe, the circuit size is determined by the specific oven that will be installed. All ovens are not the same, such as double ovens, self cleaning ovens, and ovens located in other countries where the voltage is a factor as well. Therefore, it is best to obtain the electrical circuit information and specifications which are are found on the equipment nameplate attached to the oven, or in the installation manual or instruction which is supplied with the new oven.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
